International T/A Series [1971 Season] [Season Finished]

Community Challenges & Competitions
1

Good evening!

It’s been a while since the third International T/A series ended. 1969 was an interesting year, with several races boiling down to hundredths of a second. While there was one top contender in each class, there was good movement and battling at nearly every level. Can YOU design the next championship car?

WAIT, WHAT’S THIS? 1971? WHAT HAPPENED TO 1970?

Long story short, there was little change in rules historically in T/A racing in those years, so I could drone on another year with lowering levels of interest, or I could skip to the next major year of rule changes.

[size=150]International T/A Series[/size]

My objective with this is to roughly simulate the American Trans-Am series, now entering the “Golden Years” where AMC, Ford, and Chevy duked it out with their pony cars, as Datsun and Fiat battled in the smaller displacement class. Like those years, there will be two different classes with radically different engine designs. Participants may enter into one or both categories. Since T/A was eventually a manufacturer’s championship, the car and the engine must be designed by the same entity – no purchasing engines from other companies. Also, there will be valvetrain (and other) restrictions to stay in keeping with what, historically, were the competitors of the day. Of course, the competition bears a LITTLE bit of my own twist to it. Being the 1971 season, nearly every major American manufacturer pulled out of the historical series after the season concluded. Thusly THIS WILL BE THE LAST SEASON FOR THE TX CLASS. Also, the lower level “Two liter” class changed in this year, both in design and name.

THERE ARE SEVERAL RULE CHANGES THIS SEASON. PLEASE READ CAREFULLY.

NOTE: Any car that throws a .LUA file error while attempting to test on any given track will receive a “DNF” and be given 0 points for that track. So please make sure your entries load on every track!

Submit your car’s .LUA file to me before the deadline. Please name your car within Automation with the following convention:

1971 ITA - (name) - (class)
example: 1969 ITA - VicVictory - TX.lua

I WILL NO LONGER ACCEPT ENTRIES WHERE THE FILENAME DOES NOT MATCH THE ABOVE FORMAT. (For those of you who have not run a competition yet and wonder why, it’s because it’s a colossal PITA to sort through all the entries when you name things all willy-nilly.)

I know you all like to name your cars. So do I. Don’t name it within automation, send the following information with your .LUA file in the PM:

Username: (Your board username)
Car Name: (Manufacture/model name for your car, ex: Ardent Thrush GT)
Nationality: Nationality of your RACE TEAM (can be fictional if you so desire)

Any questions? Comments? Desires for me to take a flying leap? Post 'em.

2

Are we able to use underbody aero? There is only the option of semi-clad but since I cannot remember if we were allowed to have this in the past I want to make sure it’s OK two years later! :laughing:

3

My only restriction on Aero is no canards. :laughing:

4

You said that front wings are prohibited, mostly because of aesthetics, I assume. But if I hide my wing in some way, can I use them?

5

I’m in

6

No, they’re disallowed as a matter of course.

7

In that case, how far forward can the wing be placed? On the front of the roof? It may be an academic question but I’m interested, so thought I should clarify…

8

Trunk if sedan/coupe, as close to the rear of the roof as possible if hatchback (Don’t remember if any hatch bodies were even available in that year)

9

Is my spoiler placement okay? I sent the .lua for review

10

I haven’t looked at it yet. Reviewing the current submissions is on my plate for tomorrow.

11

No problem. After many seasons of observing this enduring title, I’m prepping a car for entry!

(I then fell afoul of the “using certain characters in the name breaks the save and your file gets wiped too bad so sad” thing, and lost the entire car, and rebuilt it in five minutes and somehow it came out faster than the original…)

12

So does that mean my personal favourite method of wing placement (lip on front; lip on bootlid and small wing just above rear window) is now illegal?

This would make me sad as I do this for aesthetic reasons and it balances my car well without causing DNF’s… :frowning:

13

Yup.

(Blame strop… he made me answer the question.)

14

okay, I’m confused. The rule is one lip on the front and one wing or lip on the rear? or nothing on the front at all?
Also can we change the gear ratios for each track? or do we need to figure out some ratio we stick with and cross our fingers? Because at the moment my car will kick ass on Laguna Seca but will have its own ass handed to it on a track with some longer straights haha
At the very least allow us to change the final drive, yes?

15

The only thing that is out as far as aero is placing a wing on the front… and the position of the rear spoiler must be on the trunk lid (sedan) or top of hatch (hatchback).

As per the OP, Alternate transmissions are not allowed this time around. You run the one you submit the car with.

16

huh, I didn’t think you meant the same ratios too… hmm… this could make things very difficult not knowing what tracks I need to gear this for.
Ah well, I guess I’ll just pick a nice balance between acceleration and top speed and cross my fingers that the track types remain consistent

17

5 of the 8 tracks are now listed on the front page. Still deciding on the last 3.

18

Talking of the flying laps, I vote for the times to be taken that way.

19

[quote=“VicVictory”]Yup.

:o

Haha jokes. Better than submitting a car with the wing on the roof of a sedan only to be told it wasn’t legal (which was what I had originally planned to do, whoops!).

Gryphon Gear didn’t exist in 1971. However, a couple of major British marques were in their hey-day then. So it was that a small crew of opportunists tried to jump on the bandwagon and get in on the action.

As I am discovering, the car is rather underpowered… so if it doesn’t win any races, maybe it might win a fashion contest…
